AI Technical Summary

Technical Problem

Many mobile computing devices, particularly smartphones and tablets, lack the capability to output content to external displays, especially multiple displays, and do not scale video resolution to match the external display, resulting in a poor user experience for productivity and multitasking applications.

Method used

A multi-screen controller for mobile computing devices that receives pixel data from third-party image sources, aggregates and transcodes it into frames suitable for multiple displays, bypassing the device's operating system limitations, and outputs the transcoded data to a docking station for display.

Benefits of technology

Enables mobile computing devices to output high-resolution content to multiple external displays, enhancing productivity and multitasking capabilities by acting as an intermediary between third-party image sources and docking stations.

Abstract

This disclosure provides methods, devices, and systems for processing content for multiple displays. The present implementations more specifically relate to outputting video content from a mobile computing device to multiple displays coupled to a docking station. In some aspects, a multi-screen controller for a mobile computing device may receive pixel data associated with multiple displays from one or more image sources and may aggregate the received pixel data into multiple frames associated with the multiple displays, respectively. The multi-screen controller transcodes each frame of pixel data, from a first video coding format associated with the one or more image sources to a second video coding format associated with a docking station coupled to the displays, and outputs each frame of transcoded pixel data to the docking station for display on a respective one of the displays.
